Green Transportation – No Bailouts Necessary

Green Transportation – No Bailouts Necessary

Unless you have been trapped in a cave for the last seven months you are well aware of the disaster overtaking the American automobile industry. Our government is using billions of taxpayer’s dollars to prop up an industry that has been one of the leading facilitators of numerous ills in our society, which will also take billions of dollars to repair, if it is even possible to do so. 

Air pollution which contributes to increased medical costs, urban sprawl, a negative balance of payments from importing oil and global warming can all be traced at least in part to our addiction to the automobile. Now that I’ve ranted about the autos effect upon our society I also greatly acknowledge that we all, myself included, greatly enjoy the mobility and freedom provided by the pernicious machine. We can’t live with ‘em and we can’t live without ‘em. What are we to do?

A lot has been written about the currently nonexistent plug-in electric car. This machine when it finally hits the market could help solve some of our problems but current pricing estimates place the car in the forty thousand dollar range. I’m sure of one thing, it won’t solve many problems if you don’t sell them and at that price I’d hedge my bets.

However, there is one personal transportation option on the market that fits into all of President Obama’s initiatives for energy self sufficiency, global warming (reduction of green house gases), health care (exercise and weight loss), environmental protection (reduction of air and water pollution), and infrastructure renewal.   That option is the Electric Bicycle.

The electric bike using lithium batteries (traditional lead-acid is very environmentally harmful) can go, depending on load factors and riding habits, roughly twenty miles at twenty miles an hour on one charge. It is almost completely silent, gives off no emissions, does not use foreign oil, does not require much room to operate or park, never needs a tune up and provides exercise. It eliminates many of the drawbacks of riding a traditional bicycle for basic transportation while having few of its own. I recognize that not many of us are hardy enough to ride a bike in the rain, snow or freezing cold but that applies as well to motorcycles, motor scooters and traditional bicycles. The electric bike can get you farther, faster without arriving at your destination soaked in sweat. It can operate in many places where other motorized vehicles cannot and makes taking hills a cinch. Riding five or ten miles to work is no big deal and you can simply pedal around bottled up traffic. Usually the lightweight batteries easily detach from the bike and can be carried into your place of work or school for recharging.

Some electric bicycles offer high tech extras such as LiFePO4 batteries that are good for a thousand recharges, regenerative braking that helps recharge the battery much as a Prius does, and internal gearing to generate more torque for uphill climbs. Most electric bikes use what is referred to as a hub motor. This is not a traditional gear or belt-drive motor but is built directly into the hub of one of the wheels. This motor contains two internal rings of opposing magnets that when power is applied causes the wheel to spin. Such motors need little service and never require oil changes, spark plugs or new belts.

Electric bikes come in several of styles. There are the traditional “beach cruiser” and mountain bike styles as well as electric folding bikes, tricycles and “road bikes”.   The electric folding bikes are particularly interesting. Smaller and lighter than a traditional bicycle, they easily fold up and fit into a car trunk and can be carried on a commuter or subway train with little effort. You can take the train to your stop, unfold the bike and pedal on your way. They are also useful for those who live in tight quarters and have no external place to store their ride.

For those of you that are moderately handy with tools, there are a number of electric bike kits on the market that allow you to adapt an ordinary bicycle into an electric bike. One company, Worldwide Electric Bikes, has a particularly well-designed kit that has many of the features I previously mentioned. These electric bike kits do not require a high level of mechanical ability to install. A few common hand tools, a basic understanding of how things go together and the ability to read directions is all that is required. However, if you don’t know the difference between a crescent and a hex wrench, you may wish to buy a pre-made bike or have someone install the kit for you. If you do choose to go the kit route, you can end up with a much more powerful and sophisticated bike for substantially less money than a factory built electric bike. 

Electric Bicycles in all forms have long been a staple of personal transportation in Europe and Asia where there are hundreds of thousands in operation. In the United States bicycles have traditionally been dominated by the toy or recreation market or for the dedicated enthusiast. In both Europe and Asia, cycling has been a traditional means of basic transportation. I believe that this is going to be more and more the case in this country. People are avidly seeking relief from the high financial and societal cost of automobiles. The electric bicycle, while not a panacea, is definitely poised to help provide a portion of that relief.

Electric Bicycles are inexpensive to purchase, require no license or insurance, have a negligible cost of operation and are totally “green”. So, what’s not to like?

Are Tsunami’s Caused by Global Warming ?

Are Tsunami’s Caused by Global Warming ?

Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.

Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.

Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?

Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.

Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.

We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.

One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.

Water Efficiency

Water Efficiency

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

• Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
• Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
• Geothermal power plants add another 2 billion or so gallons a day.
• Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

• The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
• At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
• The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

• Stretches below dams are often completely de-watered.
• Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
• A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
• By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
• The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
• This often eliminates native populations of fish and other wildlife.
• Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
• As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.

Recycling of Electronics

Recycling of Electronics

Society’s technological advancements have grown significantly over the years. Electronics devices such as telephones, cell phones, radios, CD and DVD players, televisions, and computers are products that are used in every household. These items are just a few of the many electronic devices that can cause serious environmental damage due to their toxic components. Electronics that are in need of disposal are referred to as e-waste, or electronic waste. Because of the advancement of electronic products, there has been a growing concern about the hazards of electronic waste. Some of these concerns include: improper disposal of toxic materials, health and safety concerns for people disposing of these items, as well as dangers to the soil and water supply. For instance, electronics are made using a considerable amount of toxic substances such as lead, cadmium, aluminum, zinc, copper, and plastics which can all leak poisonous material in the ground and water. These environmental concerns have resulted in the establishment of electronic recycling facilities and industries who take old electronics such as computers for the purpose of recycling and safe disposal.

Electronics containing materials such as metals, plastic, are valuable to the recycling companies. Disposing of electronics through a recycling company will result in fewer electronic devices going into landfills and lower carbon emissions.

Recovering Raw Materials: Recycling electronics involves recovering raw materials from the electronic equipment. Materials such as steel, copper, wires, aluminum, brass, plastics, glass,etc., are extracted and sold to smelters so they can create raw materials. Depending on the type of metal being extracted, they can be processed and used in products required by such businesses as the steel, construction and cement industry. Plastics and wood can be used as fuel to provide heat to industrial furnaces which converts to steam. Metals such as copper are sold to metal refineries.

Plastics: Plastics from such items as computers, computer mice, and keyboards, are sent through shredding processes and machine sorted. They are then sent to other recyclers for further processing.

Larger Electronics: Items such as televisions and computer monitors are dismantled by hand. The leaded glass cathode ray tubes are removed and disposed of safely. Plastics, copper, and circuit boards are removed, separated, and processed.

Hazardous Items: Toxic items are removed from electronic devices and disposed of safely. Toxic substance can include leaded glass, rechargeable batteries, non-rechargeable batteries (i.e.alkaline, lead acid, cell batteries) mercury in lamps and switches, parts containing polychlorinated biphenyls, as well as ink and toner cartridges. The remaining non toxic materials are processed and the recyclable materials are recovered. The materials are shredded and separated according to type. For instance, they can be divided into such materials as steel, copper, aluminum, and plastic.

Refurbished Electronics: There are now many companies that acquire used computers, repair and update them, and resell them at a much lower price. This is a great way to keep electronics out of landfills and make technology more affordable.

Donate Your Computer: If you are getting rid of your old computer because of a recent upgrade, consider donating it to charity. Many schools and non profit organisations are in need of computers. There are companies and businesses that will take your computer, refurbish it, and donate it to a needy cause. Make sure your computer is wiped clean of all information before donating it. Donating your computer helps the community and the environment.

We are fast becoming a technology dependent society. When it comes to protecting and conserving our environment, we have to adapt and change our technological practices to ensure a sustainable future. Recycling electronics is a great way help the planet.

Know that repairing a computer or laptop repair Toronto is not cheap, but it can be cheaper than having to replace the computer. If you run into these situations, you will need to hire a onsite computer repair service Toronto.

Climate and Biodiversity For Common Good

Climate and Biodiversity For Common Good

Concerns about dangerous climate change and large biodiversity loss are visible throughout the world: unprecedented rates of temperature increases and species extinctions are a reality. In 1999 Dr. Peter Raven, president of the International Botanical Congress, published a paper in which he states that “current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue. At this rate, one-third to two-thirds of all species of plants, animals, and other organisms would be lost during the second half of the 21st century, a loss that would easily equal those of past extinctions”. He then outlined seven “Points to Slow the Extinction of Plants”, including financial and capacity building instruments to help developing countries protect 80% of the world’s biodiversity they host. As far as climate change is concerned, the responsibility of developed countries is high in providing the most threatened regions in the world with good instruments to cope with this challenge (or at least examples of them to implement autonomously).

Climate change plays a significant role in this human-induced mass extinction because it is increasing the already large biodiversity losses caused by habitat destruction and fragmentation, water and air pollution, introduction of invasive species. Marine ecosystems will be affected by an increase in sea temperature, but also by ocean acidification, because of the higher concentration of dissolved carbon dioxide (carbonic acid): in fact this reduces the shell formation ability in many organisms. Polar (and mountain) ecosystems are particularly vulnerable to climate change, with effects such as thawing permafrost, decreased snow cover, losses from ice sheets and changes in ocean temperatures. Large impacts on Arctic biodiversity are already evident, pictures of polar bears wandering lost on small icebergs being a scary and sad symbol of the era we live in (even former U.S. President Bush, at the end of his mandate, recalled this image to show his fellow citizens he cared about climate change …)

In this rapidly changing environment it is therefore extremely important that conservation plans include adaption measures for ecosystems accordingly to the predicted regional climate patterns (but models need still to be improved a lot at this scale): dynamic approaches are needed to set good options for future ecosystems and landscapes. It will be necessary to facilitate the movement of species to new geographical locations, as they follow the shifting habitats.

The public concern is growing: in Africa last 28 February young people organized a march from impoverished urban areas to the summit of Mount Kilimanjaro to raise awareness on climate change, together with the Kilimanjaro Initiative and the UN’s global UNite to Combat Climate Change campaign. It seems though that the global attention on climate change doesn’t fully consider implications for biodiversity yet: while the negotiations and speeches on climate issues are very popular (and the Nobel Prize was awarded to the entire IPCC together with Al Gore in 2007) the meetings and decisions of the Convention on Biological Diversity (http://www.cbd.int/) don’t raise comparable interest. Is it because the anthropocentrism is (still) the prevailing philosophy and animals and plants are mainly seen by people as beautiful “supporting actors” on the planet we live on? Right when we are losing control of the global situation it is probably time to reflect on our role of dominant species and acknowledge the fundamental contribution of other organisms to our livelihoods, despite many of us live in the so called Technosphere.

Policies to protect the climate avoiding irreversible effects on the ecosystems need to be strongly interconnected with conservation strategies: preserving natural areas while helping them adapt to the changing climate means hopefully to leave better, or not as compromised, ecosystems to future generations. Climate and biodiversity, though ever changing and evolving, are common goods and they need common policies: if we reduce the human Ecological Footprint both the atmosphere and the biosphere will be better off (and our children and grandchildren living in them).

The Ecological Footprint is a measure of human demand on the Earth’s ecosystems. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. For 2005, humanity’s total ecological footprint was estimated at 1.3 planet Earths – in other words, humanity uses ecological services 1.3 times faster than Earths can renew them.

Helping Kids Care For the Earth – Ideas For Earth Day and Beyond

Helping Kids Care For the Earth – Ideas For Earth Day and Beyond

Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.

It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:

1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.

To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.

If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.

2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.

3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.

4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.

5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.

6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.

In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

Home Bio Diesel Production

The flammability point of biodiesel.

I’ve mentioned that it’s biodegradable that it’s safe to use blah, blah, blah, all these different things, but I want to show you how safe this is. This biodiesel, I’ve made from canola oil, so I’m going to pour a little bit in here, and now it’s time to play with fire. We’re going to come down here. Light up our torch, notice I have my fire extinguisher people.

We now have a nice blow torch going. Notice I’ve got some nice biodiesel on the ground here. I want to show you that biodiesel is very, very safe to have around. I can’t light it on fire. This torch is a really hot torch. I’m actually using map gas. Map gas actually has a higher flame temperature. So I’m just trying to light this sucker on fire, and you know what, she’s not going. That’s because biodiesel isn’t actually that flammable. It has a much higher flash point than normal diesel, and I’ve just proven it.

And that’s one of the reasons people like biodiesel is because it’s so safe to use. In fact, if this stuff spills on the ground the MSDS and things that it calls for is get a garden hose and wash it off. It’s not going to light up. It’s as safe to have around as vegetable oil. No I have to cavy up that this biodiesel has been cleaned. We have got all the methanol out of it, and we’ll talk a little bit about that later, but I just want to show you that it’s very clean and it just doesn’t burn. That’s that little fun experiment. We want to show you that biodiesel will burn though. When it’s under pressure it does burn quite well. For this experiment I’m just going to start a fire, and I’m going to spray it into it. As you can see it will burn, so when it’s in your diesel and it becomes injected, it will burn beautifully. That’s biodiesel burning.

Both Man and Nature Cause Global Warming

Both Man and Nature Cause Global Warming

It will take all of us to make a significant impact in the world against global warming. The earth is in trouble because of the pollution that we may have caused. It would seem that we are apathetic to the earth’s plea for help. Every natural disaster that is happening to the world, to us, is caused by us. We may have caused it directly or indirectly.

One of the more significant effects of the damage that we have caused this planet is global warming. We may have been feeling how it is a little warmer, how the seasons are all in disarray. It is cold when it should have been hot and it is hot when it should have been cold. Typhoons are also stronger than ever before, aside from the fact that it is more frequent. And haven’t you noticed how a little rain could cause floods? Don’t you find that weird? Well, these are all the effects of global warming and we should be alarmed by it.

That is why natural and environmental causes such as the earth day should be supported because aside from minimizing the use of electricity which is by the way one of the causes of global warming. It brings about social awareness to inform those who are oblivious to what is happening to the world and it re-educates those who are aware. Information is the key and it may be the cure if we do it together. Great things are going to happen. Just the recent earth day brought about great changes that will be felt by the people for generations to come. Can you just imagine the positive effects that this will bring to mankind? Earth will benefit if it continues yearly. Who knows maybe one day global warming will no longer be a problem.

The Honey Bee Crisis – Believe Me It’s Bad!

The Honey Bee Crisis – Believe Me It’s Bad!

“My Oh My” this is getting serious. What is happening to our honey bees? We have been starting to see the actual effects of the honey bee decline after placing our last order for bulk beeswax. As a manufacturer of natural beeswax lip balms and candles we have always been getting our beeswax here in our home state of Florida and last month was the first time we had to order from outside the sunshine state. Is this due to the rapid decline in honey bees or are we just worrying too much? Well facts are facts and we have some serious problems with the honey bee decline. Why are the bee colonies down as much as 60% we ask? Well it does seem that bees and humans may have something in common. Nutrition is as vital to us as it may be to the honey bees and it is possible that the bees are undernourished which may be the cause of the problem. Many states are seeing less dense bee hives and this may be contributed to the lack of nutrition the bees are getting.

Another possible cause of the honey bee crisis may be the pesticides that are being used. Many hives die as a result of “pesticide poisoning”. There are literally billions of honey bees dying prematurely and the source must be found before this world suffers severely. The honey bee only has a six week life cycle in the summer, three weeks inside the hive and three weeks outside, but many are not even making it to the fourth week.

So yet another possible source of this dilemma is the huge rise in cell phone stations and also cell phone use. Some are claiming the huge growth of clogged air waves with cellular waves may be disturbing the bees and causing the early deaths. Stephen C. Sharp who has been studying this problem for many weeks while not a scientist gives no personal merit to this cause. He states “Cellular phones have been around for long enough to see a potential problem with the bees. This problem came like a train wreck. I think there would have been many initial signs if the cellular wavebands were the source of the bee problem.”.

Other topics that have been thrown around as to the potential source of the bee crisis has been a virus or possibly mites that have worked their way into the bee colonies. Whatever the cause it must be isolated and controlled. Bottom line is if the bees all die maybe we will too! Bees are the only source to carry pollen of various fruits and nuts. Many plants do not reap the benefits of wind travel for pollination therefore if the bees vanish so does much of our food supply. We would begin to see a decline in new plants, brush, flowers, crops, and more. The honey bee gets food such as nectar and pollen from flowers and in turn pollinates the flower which allows the plant to reproduce. No bees, no reproduction!

Sincerely,

Stephen C. Sharp

How to Address Contaminated Land Issues

How to Address Contaminated Land Issues

Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.

Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.

The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:

• environmental baseline conditions
• potential environmental impacts
• mitigating measures
• residual environmental impacts

There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.

Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.
